JEWELERS PUNCH.

Application filed July 28, 1919.

To all whom 2'25 may concern.

lie it known that I, BRUNO .V. Bon'rrre- HEIMER, a citizen of the United States, and a resident of the borough of Brookl n, county of Kings, city and State of ew York, have invented certain new and useful Improvements in Jewelers Punches, of which the following is a specification.

The present inventionrelates to jewelers punches, and-particularly a punch intended for removing rivets from articles of jewelry, such for instance as the small rivets used to form a hinge for the pins of brooches and the like. An object of the invention is to provide such a device which will enable the removal of such rivets with facility and without danger of injury to other portions of the article as has been the case with the means heretofore employed for this pur pose and the use of which very often resulted in the mutilation and injury of the articles especially when such articles were of a delicate nature. Another object is to enable the support of the article in a manner as to make the removal of the rivet positive and true, and at the same time will give the person using the same such free use of his hands as to properly carry out the punching operation. A still further object is to provide in such a device a supporting plate having different sized openings there in which, by adjustment of the plate, wlll enable the removal of rivets of various sizes and with the same degree of care and elimination of the danger of injury to the article. While the present disclosure is especially intended for use by jewelers, it will be understood that the invention will be adaptable to other analogous uses.

With these and other objects in view, an embodiment of my invention is shown in the accompanying drawings, and this embodinient will be hereinafter more fully described with reference thereto and the invention will be finally pointed out in the claims.

In the accompanying drawings,

Serial No. 313,745.

Fig. 5 is a side view thereof; and

Fig. 6 is a detail vertical sectional view enlarged, showing the manner of using my improved device.

Similar reference characters indicate corresponding parts throughout the several figures of the drawings.

Referring to the drawings, the embodiment of my invention shown therein com-- prises a frame consisting of a base 10, relatively fiat to form a substantial support, and prov' ided at itsforward end with an upright post 11, while at its rear end an arm 12 extends upwardly therefrom and is carried forwardly over the post, being provided at its end with an elongated bearing 18 having a vertically disposed passage 14 extending passage being forwardly of the post.

A passage 1-5 extends upwardly through the post 11 from the under side of the base, the said passage being reduced and screw threaded at its upper end as at 16 and having a screw 17 engaged therewith and projecting upwardly above the post to form athreaded upstanding stud disposed forwardly of the center of the post.

A centrally perforated plate 18 is disposed upon the upper flat side of the post, the perforation thereof engaging the stud 17, the periphery of the said plate being beveled and provided with a plurality of radially disposed openings or cut-outs 19 of different sizes and adapted by rotation of the plate to be brought into alinement with the punch 20 slidably disposed in the passage 14. The plate is held securely upon the post by means of a nut 21 engaging the threaded stud and at its forward portion projects beyond the post to provide a free space beneath the opening in alinement with the punch to permit of the removal of the rivet as will be presently more fully pointed out. The tapered end of the punch may normally rest in the opening when the device is not in use.

When it is desired to remove a rivet, the article containing the same is placed upon the plate as shown in Fig. 6 so that the rivet is above the opening and in vertical alinement with the punch whereupon by tapping upon the upper end of the punch with a hammer or other suitable tool, the rivet will be forced from the article and removed through the opening of the plate.

By providing various sized openings in the plate, slightly larger than the diameter of-the rivets, any danger of marring or injuring the article is eliminated as the support of the article by the plate is very close to andat each side of the rivet. Should an opening of large size be used inrremoving a very small rivet, it Will be understood. that the surrounding portion of the article Would be bent in removing the rivet and it is this condition that is removed in the present invention by providing the openings of vathrough its outer edge and extending at one a side beyond the post in alinement with the 7 bearing, said post being free of portions projecting beneath the plate at opposite sides of the slots at the point Where the plate extends beyond the post, means to adjustably hold the plate on the post, and a punch means loosely engaged through said bearing and adapted to enter through the slots in the plate.

2. A jewelers punch comprising a base having a passage entering the same from beneath said passage reduced at its upper portion and opening through the top of the post, a headed stud placed in the passage and provided with a shank extending upwardly from the post, a disk supported on the upper end of the'post and rotatable about the shank, said disk having: radially-arranged slots opening on its edge and being of differcut Widths, the disk extending at one side he yond the post, means engaging the'shank to clamp thedisk against rotation, and a punch element guided above the post and ofiset therefrom into alinement with the portion of the disk extending beyond the post.

In testimony that I claim the foregoing as my invention, I have signed my name here under. 7
